      abstract     = {Interstellar magnetic field is essential in various
                      astrophysical phenomena and processes. Pulsar halos are a
                      recently discovered class of TeV gamma-ray sources formed by
                      escaping electrons/positrons from pulsars. The morphology of
                      the halo is regulated by the diffusion of those escaping
                      particles, and hence carry information of the interstellar
                      magnetic field. We suggest that the morphology of TeV pulsar
                      halos can be used as a novel probe of the properties of
                      interstellar magnetic field around the pulsar, such as the
                      $Alfv\'{e}nic$ Mach number and the mean direction. We
                      establish a theoretical relation between these quantities
                      and the observational features of the halo's morphology
                      based on the anisotropic diffusion model, and show that how
                      X-ray observations of the pulsar halos can further improve
                      the diagnosis of the magnetic field. Lastly, we try to apply
                      our method to an observed pulsar halo candidate,
                      HESS~J1809-193, as a practical example.},
